RDM6300 125KHz cardreader mini-module is designed for reading code from 125KHz card compatible read-only tags and read/write card.
Sensor uses serial interface for communication.
| RDM6300 | ESP8266 |
|---|---|
| TX | GPIOx |
| RX | GPIOy |
| Pin3 | unused |
| GND | GND |
| VCC | 5V |
In the Configuration -> Configure Module page assign:
- GPIOx to
SerBr Tx (71) - GPIOy to
SerBr Rx (72)
If the RFID Tag is held in front of the Antenna the reader starts sending the Tag ID. The Tag Id is prefaced with a 0x02 and the end is delimited with a 0x03. If the reader reads the tag multiple times you would get one line with multiple times the Tag ID. For this to seperate you can add a SerialDelimiter of 0x03. This will split the result from the serial into serveral single mqtt messages. But (probably) all the messages wil be prepended with a binary 0x02.
Set SerialDelimiter to 3
SerialDelimiter 3
